Fixing Season Specific Tile Problems

Hey guys! So I've been back playing 1.5, with absolutely no problems so far. I've got a few mods & I have some basic experience editing xnb files and customizing maps. I just got to Winter and I suddenly noticed 2 glaringly weird issues that definitely were not there in the other seasons. I looked at the winter tile sheets and even double checked the maps in the map editor and nothing. It was Fall everything looked great I went to sleep without reloading walked around Winter 1 and it looked weird so it's definitely something about Winter. I can probably fix it myself I just really don't know how to go about doing something like that since I've never worked on anything seasonal. Does anyone have any idea what might have actually happened?
